Is this at all possible? I'm a "downsized" engineer (merger/acquisition, blah, blah) who designed a number of automotive ignition products using Atmel devices. One popular product used the long-obsolete AT90S4433 device, which was replaced with the mega88 in the design. However, due to the fact that the new owners have no interest in supporting the older product line, I am doing repairs on these ignitions at home. I use Studio 7 for firmware work, and I have made some upgrades to the ignition firmware that I'd like to be able to incorporate into the older 4433-based ignitions, but Studio 7 does not have support for that device.

Is there any way that this can be added? The alternative is to replace the existing part with a mega88, but that is fairly labor intensive, and often results in damage to the PCB as the part is removed.
